Patented Apr. 8. 1884 UNITED STATES JOHN J. VINTON, OF YOUNGSTOIVN, OHIO.

SPECIFICATION forming part of Letters Patent No. 296,369, dated April 8, 1884. Application filed February 4, 1884. (No model.)

To all whom it may concern Be it known that I, JOHN J. VINTON, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful Mold for Repairing Broken Rolls, Shafts, &c., of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved mold for repairing broken rolls, shafts, and other similar castings; and it has for its object to provide a simple,convenient,and efficient apparatus for the purpose stated.

To this end it consists, essentially,.in certain improvements in the construction of the mold,which will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a vertical sectional View of the mold in position for operation. Fig. 2 is a horizontal sectional view on the line as a: in Fig. 1.

The same letters refer to the same parts in all the figures.

A in the drawings designates the broken end of a roll or shaft. This is set in abed, B, of sand, loam, or the like,with the brokenend projecting, as at G.

D designates the mold,which is constructed around the projecting broken end of the shaft or roll, as shown. Said mold comprises the lower portion, E, which is made in two partsan inner lower part, E,'and an upper outer part, B, the central mold, F, and the top portion, G. The latter has a concave upper side from which a series of gates, K, lead through the central mold, F, to the broken face of the shaft or roll. The latter is surrounded by the bottom mold, E, in which a series of radial passages, H H, lead to a circumferential channel, I, having an outlet, J. The sand bed B is usually the foundry-floor. The several parts E, F, and G of the mold are made of dry sand. The neck of the roll is formed in the partE of the mold and the wabbler in the part F. The gates K are preferably five in number, three only being shown.

,In operation,after building the mold around the broken end of the article to be repaired, the molten metal is poured in through the gates K, which direct it against the broken surface, from whence it is deflected through the passages H into the circumferential channel I, and thence out through the outlet J. The heat of the molten metal soon fuses the projecting broken .end 0, and as soon as this takes place I stop the outlet J with a plug of clay, loam, or the like, and continue filling the mold until the latter is full. After the metal has set and hardened I proceed in the usual manner to remove the mold and finish the casting.

I claim as my invention and desire to secure by Letters Patent of the United States The herein described mold for repairing broken rolls and shafts, consisting of the lower portion, E, made in two parts, with the central opening for the broken end of the broken roll or shaft, and the radial passages and circumferential channel having the outlet J, the central or wabbler section, F, and. the upper or basin section, G, provided with the gates K, leading to the wabbler and neck sections, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JOHN J. VINTON.
